Abstract

The utility model relates to an LED lamp cup, consisting of a lamp cap, a housing, an LED illuminating element and a radiator, wherein, the outer surface of the radiator is provided with radiating fins and radiating columns, the LED element is arranged on the inner surface of the radiator, the air out of the lamp body can pass through an air vent on the housing and flows the gap between the radiating fins and the radiating columns so that the heat generated by a chip is rapidly radiated, thereby ensuring that the temperature rise of the LED chip is kept at a low level, fulfilling the purpose of delaying the light decay process and prolonging the service life of the lamp, and having good social and economical benefits.

Description

A kind of LED cup lamp

Technical field

The utility model relates to lighting device, is specifically related to the LED lighting technical field.

Background technology

Existing LED cup lamp is high-power LED cup light particularly, the design of many employing enclosed constructions, its radiating fin only is distributed in the side of lamp housing, and the back of LED is encapsulated in the lamp housing, fin generally is not set, the air of shell inside can not be with the outside air convection current, the caloric requirement that such structure makes led chip produce is delivered on the radiating fin of lamp housing side through long thermally conductive pathways, its heat conductivility and heat dispersion are not good, cause heat in the lamp housing inner accumulated, must cause the led chip temperature rise too high, accelerate the light decay process of chip, the useful working life of chip and lamp life are shortened.

Goal of the invention

The purpose of this utility model is exactly will the structural design of LED cup lamp be made improvements, and makes that its heat conduction and heat radiation performance is better, reaches the purpose that improves lamp life and then improve its economic results in society.

Summary of the invention

Technical solution of the present utility model is: at the front end position of Lamp cup housing a radiator is set, the design of radiator outer surface has radiating fin or thermal column, the LED light-emitting component is mounted on the inner surface of radiator, on Lamp cup housing and the corresponding position of radiating fin, design has a circle heat radiation pore circlewise, the lamp body air outside can be flowed through each pore from the four sides direction and be run through gap between radiating fin or the thermal column, said radiator is formed by aluminium matter or copper or alloy material die casting, also can process, also can be processed into by aluminium alloy extrusions by above-mentioned material car plane.

Technique effect

The heat that this novel Cup lamp structure makes led chip produce can be transmitted on the radiating fin or thermal column at the back side with very short path, then be dispersed in the air, because air can connect from lamp body four sides direction, hot-air can exchange with outside air again apace, obviously more excellent than the existing enclosed construction heat dispersion that does not connect, adding has increased cooling surface area, further strengthened heat dispersion again, the enhancing of heat conduction and heat radiation performance, the temperature rise that just means led chip will maintain a lower level, thereby will slow down the light decay process and improve life of product.

Description of drawings

Fig. 1 is the utility model LED cup lamp example structure schematic diagram;

Fig. 2 is the vertical view of A-A section among the embodiment.

The specific embodiment

See also accompanying drawing, the utility model LED cup lamp is mainly by cap part 1, Lamp cup housing parts 2, compositions such as radiator 3 and LED light-emitting component 6, the outer surface design of radiator 3 has some quantity radiating fins 4 and thermal column 5, LED light-emitting component more than at least one is mounted on the inner surface of radiator, its attaching method has following several, the one, earlier LED is encapsulated or is welded on the printed circuit board (PCB) 7, be mounted on the inner surface of radiator again, the 2nd, earlier LED is encapsulated or is welded on aluminium base or the copper base 7, be mounted on the inner surface of radiator again, the 3rd, led chip directly is encapsulated in the inner surface of radiator, and so on.The required power supply module module 8 of cup lamp is placed in the Lamp cup housing, and dividing plate 10 packings are arranged, and power module has two power input lines to be connected with lamp holder according to a conventional method, and two power supply output lines are connected with led circuit in addition.Said Lighthead assembly is meant the particular design lamp holder of various standard specification lamp holders or non-standard specification.The port of radiator and lamp housing can be with seal cover and glass or 9 sealings of optical lens part, so that protect the LED element and be beneficial to bright dipping.Obviously, the lamp body extraneous air can pass pore 11 on the Lamp cup housing from the four sides direction, flow through between radiating fin and the thermal column the gap and take away the heat energy that led chip produces, have more excellent heat dispersion.
